几年来,我们在推广杂交水稻施用穗肥的同时,还进行了不同土壤肥力、不同禾苗长相施用不同穗肥量以及不同施用时期和不同穗肥种类的试验,试验结果表明,除一个一类禾苗因生长太旺,施用穗肥后导致病虫害而减产外,其余均比不施穗肥的每亩增产40—127斤,增产率4.6—17.4％;比不施的株高高1.1—4.1厘米,包颈率低8.4—
In the past few years, we have also experimented on the application of panicle fertilization to hybrid rice with different soil fertility, different panicle seedlings with different panicles, different application periods and different panicle types. The results showed that, except for one kind of seedling Due to the growth of too prosperous, after the application of panicle lead to pests and diseases and reduce production, the rest than the non-panicle per mu yield 40-127 kg, the rate of increase 4.6-17.4%; 1.1-4.1 cm higher than the plant height, Low neck rate 8.4-
